CUDA Hardware Support

The LEADTOOLS H.264 and H.265 codecs can use NVIDIA CUDA hardware acceleration on computers with NVIDIA graphics cards with CUDA capabilities. You do not need to install anything extra to take advantage of hardware acceleration.

The codec interfaces provide supports for querying whether hardware compression is possible and enabling it. For more information on how to do this, refer to the codec interface documentation.

Not all CUDA-enabled graphics cards support both H.264 and H.265 compressions. The following table is a summary of NVIDIA hardware support for H.264 and H.265 compression used by the LEADTOOLS H.264 and H.265 codecs. For more specific information about CUDA support, refer to https://developer.nvidia.com/nvidia-video-codec-sdk.
